	Should we be performing the D-test on the few staphs isolated from urine that we perform susceptibilities on? This doesn't happen often ( a few S. aureus and pure cultures of S. epidermidis from cath specimens). We do not normally report Clindamycin and Erythromycin on isolates from urine sources.
	If clindamycin is not being considered for treatment, then the D-zone test for detection of inducible clindamycin resistance is not necessary. This would be the case for a urinary tract infection where clindamycin treatment is not appropriate. However, some labs may decide to do the D-zone tests on isolates from urine just to understand the epidemiology of Staphylococcus resistance in their institution.
